How can I get the walls I need?

[Gene Davis]

We build a lot with trusses, and our "energy heel" height is always 12 inches or more. It is common for us to do some vaulted ceilings under roof, using scissors trusses.

Chief doesn't seem to be on the same wavelength as us. Take a look at the attached wall section, drawn in Sketchup.

I can use Chief and do a roof manually (or auto), and get the roof up where it is with the 12" heel. I can also do a ceiling plane where needed, elevation-wise. I found out Chief's logic.

What I cannot do, is get Chief, when framing, to place the wall top plates as they are shown in this pic.

What's the secret? I am working in v.10.
